Katey reads more and more Agatha Christie novels. She’s come to love Christie’s novels because everyone—regardless of social standing—gets what he or she deserves in the end. Likewise, Katey knows that Mason is upset with her and pulled the prank with the wheelchair, so she takes her punishment in stride. She works harder and arrives earlier, all to try and get back in Mason’s good graces. As she sits at home one day copying out grammar rules, Anne’s assistant arrives with a handwritten invitation. She wants to refuse the invitation, but then realizes that Hercule Poirot wouldn’t turn the invitation down. She decides what to wear and goes to meet Anne. She and Anne spar a bit when they meet. Anne comments that she’s well-read for a working-class girl, while Katey shoots back that all the working-class girls she knows are well-read. When Anne mentions that sex is the cheapest form of entertainment, Katey fires back that it isn’t in Anne’s house. Anne asks Katey if they can stop being catty with each other and just talk. She explains that she had no clue that Tinker and Katey were an item. She then says that there are physical and emotional needs in relationships, and that she’s happy with Tinker being with Katey as long as he fulfills her physical needs.
